Ukraine and Russia have signed a UN-backed deal to allow the export of millions of tonnes of grain from blockaded Black Sea ports, potentially averting the threat of a catastrophic global food crisis.
A signing ceremony at Dolmabahçe Palace in Istanbul was attended by the UN secretary general, António Guterres, and Recep Tayyip Erdoğan, Turkey’s president, who had played a key role during months of tense negotiations.
